Retrieve JSON from sql - json

Question

My json format in one of the sql columns "jsoncol" in the table "jsontable" is like below.
Kindly help me to get this data using JSON_QUERY or JSON_VALUE
Please pay attention to the brackets and double quotes in the key value pairs...
{
"Company": [
{
"Info": {
"Address": "123"
},
"Name": "ABC",
"Id": 999
},
{
"Info": {
"Address": "456"
},
"Name": "XYZ",
"Id": 888
}
]
}
I am trying to retrieve all the company names using sql query. Thanks in advance

Answer 1

You can use:
SELECT j.name
FROM table_name t
CROSS APPLY JSON_TABLE(
t.value,
'$.Company[*]'
COLUMNS(
name VARCHAR2(200) PATH '$.Name'
)
) j
Which, for the sample data:
CREATE TABLE table_name (
value CLOB CHECK (value IS JSON)
);
INSERT INTO table_name (value)
VALUES ('{
"Company": [
{
"Info": {
"Address": "123"
},
"Name": "ABC",
"Id": 999
},
{
"Info": {
"Address": "456"
},
"Name": "XYZ",
"Id": 888
}
]
}');
Outputs:
NAME
ABC
XYZ

You can easily use JSON_TABLE() function for this case rather provided the DB version is at least 12.1.0.2 such as
SELECT name
FROM jsontable,
JSON_TABLE(jsoncol,
'$' COLUMNS(NESTED PATH '$."Company"[*]'
COLUMNS(name VARCHAR2 PATH '$."Name"')))
